摘　　要：生物氧化法作为预处理,联合离子交换纤维(FFA-1)技术去除水中无机砷,考察pH、再生次数对砷去除效果的影响。结果表明,FFA-1在酸性至中性条件下对五价砷(As(V))有很高的去除能力,约为90 mg/L,但是在pH为2~10时,对三价砷As(Ⅲ)去除量都很低。以生物氧化作为预处理,先氧化As(Ⅲ),再用FFA-1去除,可以完全去除水中的砷(去除率>99%)。Feasibility study on removal of inorganic arsenic from water by ion exchange fiber (FFA-1) with the biological oxidation as pretreatment was conducted.The removal efficiency of FFA-1 on arsenic is affected by pH,arsenic species and regeneration times.The result showed that FFA-1 had a high removal capacity for pentavalent arsenic (As(V)) under acidic and neutral conditions (about 90 mg/L),while had a low removal capacity for trivalent arsenic (As(Ⅲ)) at pH 2~10.Arsenic in water can be completely removed by firstly oxidizing As(Ⅲ) and then removing with FFA-1 with biological oxidation as pretreatment (removal rate of >99%).
